Abstract (en)
[origin: WO2019246501A1] A technique facilitates flow control downhole via at least one flow control valve. According to an example, a flow control valve has an internal piston. Additionally, an electrically powered actuator is mounted externally to the flow control valve and connected to the internal piston via a linkage. The electrically powered actuator is responsive to electrical inputs to shift the internal piston to desired flow positions of the flow control valve.
